I admit there is a risk that characters like Blink, Warpath, Bishop, won't be much more than eye-candy (or FX-candy). One thing that Avengers and the Dark Knight films didn't do was have too many background characters as distractions.

Well

Quote:

“I don’t want to say [who the protagonists are] yet, or talk about that yet, but I will say that every character has a very important function in the story. The story is designed and catered to the combined cast. It’s not just throwing in people to occupy the screen, occupy the billboards. The story ‘Days of Future Past,’ and our version of ‘Days of Future Past’ is geared very much toward the mass cast and all their relationships and all their foibles and their achievements.”
